FIELD: water purification.
SUBSTANCE: invention relates to technologies of purification of natural water and wastewater; it can be used for purification of water containing sulfide, hydrosulfide ions, as well as molecular hydrogen sulfide. A method for purification of natural water and wastewater is carried out by processing with a reagent, followed by settlement and precipitate separation. Processing is carried out in the presence of cationic flocculant. As a reagent, 3-10% aqueous suspension of a mixture of alkylcarboxysiloxanes is introduced, which is neutralized with iron (III) salts.
EFFECT: effective purification of natural water and wastewater containing sulfide, hydrosulfide ions, molecular hydrogen sulfide.
